5000 words on one page is a bit heavy from a design/users perspective, and from an SEO perspective, it could be better split this up over 5 pages and then you've got more web-estate to promote and rank for. Maybe just split it over X pages with 'NEXT' links between.
I, for one, switch off at giant/long pages - which remind me of those bloody-awful sales page/essay/treaties that were rife a couple of years ago. breaking things into chunks is more readable - and it seems a waste of all that original content to put it on one ranking page.
